Writing Poetry
There is an art to making words rhyme,
A rhythm that requires those words to keep time,
But master it and you will see,
There's nothing quite so creative as poetry.
Walking
Despite the obvious cardiovascular benefits, walking is a great way to clear your head, let off some steam, and just enjoy the outdoors.
Drawing
If painting isn't your thing, try drawing. Sketchbooks are relatively cheap and easy to tote so you can take your hobby with you wherever you go.
Photography
No need to spend lots of money on expensive cameras; many smartphones can now take some really nice pictures and you can always upgrade later.
Singing
Everyone — everyone — likes to sing along to their favorite songs. So, why not improve that singing voice and share it with the rest of the world?
Blogging
After you've mastered some of these other hobbies, write a blog about it!
If you have any suggestions let me know...
